Vacuum Wars named it Best Value of the Year for its balanced results: good obstacle avoidance, careful mopping and about 2,462 sq ft per charge. It is a smart buy for mixed floor homes on a mid budget. Pet owners with lots of carpet may prefer the L40s Ultra, which picked up more hair.

Shark's most capable robot so far for pet homes, with strong pet hair pickup, the best obstacle avoidance Vacuum Wars has seen from Shark and a hot wash base. The UV stain spotting works, but the mop uses a lot of water and floors can stay wet for half an hour. Skip it if you need multi floor maps or low furniture clearance.

What reviewers found
Dreame L40s Ultra AE
- Vacuum Wars (3.52 Vacuum Wars stars): 85% carpet sand removal, 81% pet hair pickup, 0% hair wrap, 19 of 24 obstacles avoided and about 2,462 sq ft per charge against a 1,015 average. Named Best Value of the Year. Source
- Just A Dad Approved (7.9/10): After 90+ days of home testing, liked the AI camera, included TriCut brush and low upkeep, but said corners get less attention without an extending side brush and recommended buying only on deep sale. Its bottom line text names a different model, so treat the score with care. Source

- Vacuum Wars (3.56 Vacuum Wars stars): Measured 0.95 kPa suction, 88% carpet deep clean, 91.5% pet hair pickup, 29% hair wrap and 20 of 24 obstacles avoided. Mopping used 3.4 to 5.3 g of water versus about 1 g average and floors stayed wet over 30 min. Source
- Ideal Home: UK test: cleared rice and oats in 1 to 2 passes on hard floors, avoided a dumbbell, found four hidden stains on its first run and measured 69 to 74 dB. The 60 day bin was nearly full after two weeks. Source
